Two-factor
authentication or two-step verification is a security feature offered by Yahoo
Mail for providing a better security to its users’ information and data.
Two-step verification works by providing an extra layer of security to a users’
Yahoo account. Whenever a user accesses his Yahoo account on a new device or
web browser, Yahoo sends a Security code to users’ phone number which is
required to be entered when signing into the account. This feature helps
prevent unauthorized log into users’ account from anyone. If you also want to
keep your Yahoo Mail account secure from unauthorized logins, you can enable
two-factor authentication feature in your Yahoo Mail account. To know how to
enable this security feature, follow the step-by-step instructions provided
below.

Steps to Enable Two-Step Factor Authentication on Yahoo Mail

1.) Sign into
your Yahoo Mail account and move the mouse cursor over your Profile Name located on the upper-right
corner of the screen. This will open the drop-down menu on your screen.

2.) Select Account info option from the drop-down
menu. You will be directed Account info
window.

3.) Under Account info window, click on the Account security option located on the
left side panel.

NOTE: You might be
prompted to enter your password in order to access Account security page. Do so if prompted.

4.) Once you get
access to Account security page,
click on the slider button next to Two-step
verification. Clicking on the slider button will take you to another page.

5.) On this
page, you will be asked to enter your mobile number which you would like to use
for enabling Two-step verification feature in your Yahoo Mail account.

6.) Enter your phone number in the prompted field and click on the Send SMS button. Yahoo will send a code to your mobile number which you will need to enter in the subsequent page that appears on your screen. Alternatively, you can also click on the Call me button to receive a code via call instead of receiving it as an SMS.

7.) Enter the
code which you receive in the provided field on the next page. Then, click on
the Verify button. Once verified
successfully, you will see a Success
message on the next page.

8.) Moreover, if
you use applications such iOS mail and Outlook to access your Yahoo Mail
account, you will need to generate a special password as two-step verification
feature will not work with such application.

9.) So, click on
the Create app passwords option
shown on the screen. However, if you don’t use any such apps to access your
Yahoo Mail account, you can simply click on Skip for now button.

10.) If later
you wish to generate an app password for an application to access your Yahoo
Mail account, simply go to Account
security page and click on the option Generate
app password option located below Two-step
verification. Follow the on-screen instructions to generate an app password
for your relevant application to access your Yahoo Mail account.

So, this is how
you can easily enable two-factor authentication or two-step verification
feature in your Yahoo Mail account.
